Recommended heroes[edit]

In general, Necronomicon is best bought by strength or intelligence heroes who have abilities that synergize with the Necronomicon summons.

  • Heroes who have creep-compatible auras.
    • Beastmaster minimap icon.png Beastmaster's Aura boosts the attack speed of all his summons, and he commonly builds more items to improve his Summoned Boars.
    • Lycan minimap icon.png Lycan gives his summons a long-duration haste, as well as providing bonus attack damage.
  • Heroes who control a lot of units.
    • Enchantress minimap icon.png Enchantress has no innate auras, but she can collect more Neutral creeps than any other single hero to gain many auras, and in the late game can control even Ancient Creeps, which work well with the Necronomicon units.
    • Nature's Prophet minimap icon.png Nature's Prophet is able to effectively increase the number of melee creeps in a lane to push it, and the summons can help speed up that push by clearing the wave and improving the move and attack speed of all the units.
    • Broodmother minimap icon.png Broodmother can at times have dozens of Spiderlings and Spiderites under her control, and the necronomicon units are an effective way of speeding up her pushing power, or to burn mana from her targets to protect her fragile summons from AoE spells.
      • In the late game, Necronomicon 3 provides her with a reliable way to keep her many webs clear of sentries.
  • Heroes with a castable attack speed buff. The Necronomicon Warrior has a very low Base Attack Time, only 0.75. There are few ways to grant it bonus attack speed, but they are very effective in increasing his mana burn potential.
    • Ogre Magi minimap icon.png Ogre Magi Can cast Bloodlust on the warrior, and slow a target to provide lots of time for the summons to burn all of a target's mana.
    • Abaddon minimap icon.png Abaddon's passive ability allows him to chase targets, and increases the attack speed and movespeed of allied units attacking the same target. It also provides him with a second reliable carrier of an aphotic shield.
  • Heroes who have channeled disables, or otherwise have spells that disable the caster.
    • Shadow Shaman minimap icon.png Shadow Shaman and Warlock minimap icon.png Warlock both specialize in summoning powerful units with their ultimates, then channeling a disable to allow their summon to deal damage. Necronomicon provides another summon to use when their ultimate is on cooldown, or synergize with their ultimate.
    • Phoenix minimap icon.png Phoenix can control summons while casting Supernova, increasing the danger to enemies who try to attack the Phoenix Sun.
  • Heroes who have damage amplification spells, but lack damage themselves.
    • Shadow Demon minimap icon.png Shadow Demon has a powerful damage amplification and multiple disables. He has the rare ability to create illusions of enemy heroes, which may in turn provide auras for necro units, as well as taking advantage of Archer Aura.
      • With the 2 summons and the 2 illusions spawned by disruption, it's possible to bodyblock a trapped enemy in all four cardinal directions, effectively trapping most heroes until one of the units is killed.
    • Undying minimap icon.png Undying gains a powerful damage amplification aura when in his Flesh Golem form, and multiple sources of slows, making Necronomicon summons particularly effective when chasing down wounded enemies. Additionally, it provides two more units to amplify Soul Rip.
  • Heroes with powerful Damage Over Time or slowing spells
    • Ancient Apparition minimap icon.png Ancient Apparition and Venomancer minimap icon.png Venomancer gain from Necronomicon units the ability to ensure that a fleeing enemy won't have enough mana to Teleport back to the fountain before their ultimate kills them, and their slowing spells greatly increase the amount of damage and mana burn that the summons can perform.
  • Heroes who can take advantage of multiple synergies.
    • Chen minimap icon.png Chen can collect ancient creeps to buff Necronomicon, and can use Penitence on enemy heroes to amplify all damage done.
    • Doom minimap icon.png Doom provides a hasting aura to his own summons when Scorched Earth is active, stacking well with Archer Aura. Using Devour, he can gain an aura to improve the summons further, and In the late game, he can Devour Ancient Thunderhide icon.png Ancient Thunderhide, allowing him to cast Frenzy (Ancient Thunderhide) icon.png Frenzy and provide War Drums Aura (Ancient Thunderhide) icon.png War Drums Aura to the summons.
    • Io minimap icon.png Io is able to summon the units after Relocating, increasing the power of a relocate gank. Additionally, if no ally needs the tether, he can Overcharge the Necronomicon Warrior for bonus attack speed.
    • Legion Commander minimap icon.png Legion Commander gains a measure of protection during a duel with the summons, Press The Attack can be used to boost the Necronomicon Warrior, and Necronomicon Archer can be used to pop Linken's sphere to allow duels.
    • Invoker minimap icon.png Invoker has potentially strong kit for Necronomicon. Alacrity provides Necronomicon Warrior with bonus damage and attack speed, Forge Spirits can reduce the armor of enemies, increasing the damage of both Necronomicon units, and he has multiple strong slows and disable to provide more time to kill off targets.
  • Some heroes have unique synergies with Necronomicon.
    • Arc Warden minimap icon.png Arc Warden is unique in that he can summon two sets of units with a single book by using his Tempest Double icon.png Tempest Double. Additionally, it extends the effective time of the double, as the summons live twice as long as the double.
      • Additionally, Magnetic Field icon.png Magnetic Field provides a way for his summons to deal more damage, and his other spells provide exceptionally strong slows to prevent escapes.
    • Keeper of the Light minimap icon.png Keeper of the Light has a kit that synergizes in many ways with Necronomicon.
      • Mana Leak will cause the target to become stunned even if another source of mana burn reduces the target to zero mana, meaning even if the target holds still, the summons will eventually trigger the stun by burning their mana.
      • Chakra Magic can be cast upon the Necronomicon Archer, allowing a second mana burn arrow after a 1 second cooldown.
      • Blinding Light can be aimed to push a target next to the summons, and provide a debuff making it harder for the target to kill the summoned units.
      • Once fully upgraded, Keeper's flying vision and the true sight aura make him extremely difficult to gank during the day, and even during the night he can use Illuminate to gain vision to deward cliffs.
    • In a similar vein, Night Stalker minimap icon.png Night Stalker's reliable flying vision synergizes well with Necronomicon for dewarding purposes, and provides him a way to burn through a target's mana during his lengthy silence and slow.
    • Dark Seer minimap icon.png Dark Seer's spells effectively amplify the Necronomicon Warrior. With Surge and Ion Shell, Necronomicon Warrior becomes an exceptionally dangerous summon.
  • Because a lot of Necronomicon's value is in its summons, Many of the above heroes gain synergy with the item even if it was purchased by another hero. In addition, some heroes are poor carriers of the item, but benefit a lot from having the item on their team.
    • Anti-Mage minimap icon.png Anti-Mage benefits from any other sources of mana burn, increasing the speed of creating the ideal target for his Mana Void.
    • Vengeful Spirit minimap icon.png Vengeful Spirit's aura naturally buffs the damage of allied summons, and her armor reduction increases the damage even more.

Strategy[edit]

  • The Necronomicon units have a very large xp and gold bounty and a long summon cooldown, avoid getting them killed unnecessarily.
  • Necronomicon is a great alternative to Diffusal Blade 1 icon.png Diffusal Blade for heroes with low attack speed who desire a source of mana burn.
  • When fighting with Necronomicon units, remember to use the Archer's active ability whenever possible for maximum mana burn.
  • In an exceptionally long game, one way to effectively use built up gold is to have a Necronomicon to carried in their backpack.
  • Necronomicon summoned units deal Piercing damage, meaning that they deal a lot more damage to creeps than they do to Heroes and towers.
    • When using Necronomicon units to push, it can be worthwhile to move one behind the tower to intercept the incoming creep wave to make sure allied creeps continue attacking the tower.
  • Against certain heroes, Necronomicon can be an exceptionally strong counter.
    • Templar Assassin minimap icon.png Templar Assassin relies on her Refraction to survive fights, which can be quickly destroyed with the fast attack speed of the two Necronomicon units.
    • Wraith King minimap icon.png Wraith King has a naturally small mana pool, and can only attack a single target at a time. Necronomicon units make it harder for him to fight the summoner, and reduce the chances that he'll have the mana to Ressurect.
    • Heroes with a small HP pool, and strong but indiscriminate nukes, like Lich minimap icon.png Lich, Lina minimap icon.png Lina, Leshrac minimap icon.png Leshrac, or Luna minimap icon.png Luna, are especially vulnerable to being killed by Last Will.
  • Necronomicon is a good long-term investment against an team with invisibility, because when upgraded to maximum level, it gives your team a mobile source of True Sight without the risk of a losing a Gem of True Sight icon.png Gem of True Sight in a fight.
    • With a freely-targetable spell that provides Vision, a support can easily check cliffs for wards with a Level 3 Necronomicon Warrior, saving on the need for Sentries.
  • Necronomicon is a good purchase to help counter an enemy with a Blade Mail icon.png Blade Mail or a similar ability which retaliates directly, because damage is reflected back to the summoned units, and it can force the target to kill the Necronomicon Warrior, taking up to 800 magical damage.
  • The Archer's Mana Burn ability is a valid spell to pop Linken's Sphere icon.png Linken's Sphere.
  • Some heroes are exceptionally strong against summoned units, and are able to deal with Necronomicon units easily. A user should avoid fighting those heroes with the summons.
    • Heroes who have strong Cleaves such as Sven minimap icon.png Sven and Kunkka minimap icon.png Kunkka are able to clear out both summons, tank the Last Will, and continue fighting.
    • While Necronomicon units are immune to Helm of the Dominator icon.png Helm of the Dominator and Hand of Midas icon.png Hand of Midas, they are vulnerable to all other forms of instantly killing or conversion spells, allowing the caster to turn back the threat of mana burn and Last Will against the original owner.
      • Of particular note is Lifestealer minimap icon.png Lifestealer who can Enrage to avoid being mana burned and being hit by Last Will, and Infest can be used on the summon to either instantly kill, or to take control of the unit.
      • Heroes who have spells which gain more effectiveness the more enemy units around, eg. Axe minimap icon.png Axe or Undying minimap icon.png Undying.
    • Heroes who can deal damage while Spell Immune or Invulnerable in order to kill off the warrior safely, such as Storm Spirit minimap icon.png Storm Spirit, Morphling minimap icon.png Morphling, or Juggernaut minimap icon.png Juggernaut.
    • Heroes who have their own summons or illusions are able to easily avoid taking the Last Will damage.

Item Synergy[edit]

  • Solar Crest icon.png Solar Crest's active reduces the armor of your enemy by 10 and applies 35% Accuracy. You can also get a Desolator icon.png Desolator to apply a similar effect.
  • Assault Cuirass icon.png Assault Cuirass: for the attack speed aura, as the Necronomicons have one of the lowest base attack times in the game so they benefit from it a lot. In addition, the armor aura doubles their physical damage resistance and it reduces the armor of enemies around. Greatly improves your pushing potential.
  • Maelstrom icon.png Maelstrom: allows you to clear creep waves faster, synergizing with the typical push style that this item encourages.
  • Shiva's Guard icon.png Shiva's Guard: make your necronomicons much tankier with the aura attack slow and gives a powerful area movement slow to catch your ennemies.
  • Rod of Atos icon.png Rod of Atos, Diffusal Blade 1 icon.png Diffusal Blade's Purge or Scythe of Vyse icon.png Scythe of Vyse's Hex for the movement slow, allowing the Necronomicons to hit more often and burn more mana (the archer's ability can be used to trigger the Linken's Sphere icon.png Linken's Sphere of an enemy, should they have one). Situationally, you can also get an Eye of Skadi icon.png Eye of Skadi.
  • Orchid Malevolence icon.png Orchid Malevolence: renders enemies unable to use spells to kill the summons, typically allowing them to live longer to cause more impact.
  • Vladmir's Offering icon.png Vladmir's Offering: grants the summons lifesteal, 4 bonus armor and 15% bonus damage.
  • Guardian Greaves icon.png Guardian Greaves and Mekansm icon.png Mekansm: grants sustainability to your summons, preventing the enemy from gaining the gold bounty.
  • Bloodthorn icon.png Bloodthorn: amplifies the damage the summons deal to the target, while rendering them unable to use spells to kill the summons typically allowing them to live longer to cause more impact.
  • Drum of Endurance icon.png Drum of Endurance: combined with the movement speed aura of the archer gives an important movement speed boost to chase enemies, split push, deward, retreat and save the necronomicons.
  • Blink Dagger icon.png Blink Dagger: is used to surprise and summon the necronomicons directly on your ennemy.
  • Boots of Travel 1 icon.png Boots of Travel: enables Teleportation to the Necronomicon summons. Additionally will cause you to gain more movement speed from Archer Aura (Necronomicon Archer) icon.png Archer Aura.
  • Heaven's Halberd icon.png Heaven's Halberd: can make a ranged carry unable to attack for 5 seconds, the 3 seconds is also good against a melee carry and the debuff can't be purged. The Maim will slow the enemy and the true sight from the necronomicon warrior make him unable to escape from invisibility.
  • Octarine Core icon.png Octarine Core: allows casting the Necronomicon more often, enabling greater uptime on the summons to deward and split push while there is no team fight.

Counter items[edit]

  • Shiva's Guard icon.png Shiva's Guard: because the base attack time is low, the aura attack slow of 45 and the 15 armor make the Necronomicon almost harmless.

Trivia[edit]

  • This item is based on the Necronomicon, a fictional grimoire created by horror author H. P. Lovecraft. The summoning ability of the item is similar to the original book's role in summoning the ancient cosmic Old Ones in Lovecraft's Cthulhu Mythos.
  • The coloration of the two units may be a reference to the Japanese tradition of Oni being either Red or Blue, with the Red Oni traditionally more aggressive, emotional, and extroverted, while Blue Oni are traditionally more serene, intellectual, and introverted.
